Arizona strikes back: State investigates feds over gun-running

Arizona's state legislature will open its own investigation into the Obama administration's disgraced gun-running program, known as "Fast and Furious," the speaker of the state House said Friday.

Speaker Andy Tobin created the committee, and charged it with looking at whether the program broke any state laws — raising the possibility of state penalties against those responsible for the operation.

It's a turnaround from the rest of the immigration issue, where the federal government has sued to block the state's own set of laws.

A law requiring businesses to check new workers' legal status was upheld by the Supreme Court last year, and the court has agreed to hear the case of Arizona's crackdown law that makes being an illegal immigrant a state crime and gives state and local police the power to enforce that law.

Fast and Furious was a straw-purchase program run by the Bureau of Alcohol, Tobacco, Firearms and Explosives. The goal was to try to trace guns sold in Arizona shops and then trafficked across the Mexican border, where they landed in the hands of drug cartels.
